Seen these motorbikes parked along the slip roads to expressways?

They are parked there to allow the LTA Traffic Marshals (LTMs) who are stationed nearby to respond quickly to traffic incidents on expressways 🏍.

As #GuardiansOfTheRoad, LTMs help to direct traffic and guide motorists in the event of incidents to keep everyone safe. They also assist in evidence preservation to facilitate investigations 🔍.
